Here's the deal...it's choices and consequences.
My kids are grown and I have toddler-aged grandkids, so I'm quite familiar with sippy cup thrills and spills
I had a friend who complained about her KoolAid stained couch. I said 'don't blame the kid blame the mommy'. Truly an AHA! moment for the mommy.
If you have a 'sippy cup-free' zone in some areas, guess what???? The chance of spills is nil.
If you permit wandering sippy cups in your landlord's carpeted residence, you are responsible when operator-errors occur.
It's a conspiracy, I tell ya. The carpet makers are in cahoots with the sippy cup manufacturers. Sippy cups give parents a false sense of security. In the olden days it was obvious, a parent could easily see the effects of sloshing and gravity. So they quickly learned (a) a moving cup caused messes, (b) to never put more in a cup than you wanted to wipe up and (c) confine the cup to easy to clean surfaces.
Carpet profits were down because vinyl and wood surfaces were not permanently damaged by spills. Soooooo, carpet makers invented a cup with a lid. Woohoo! Toddlers with lidded cups were seen lounging on sofas; building Lego enclosures for sippy cups smack dab in the middle of the living room carpet then crash landling a purple dinosaur into the carefully crafted Lego mansion. A kid could even rush to the potty with lidded cup in tow--filling the bladder while emptying the bladder. KoolAid mustaches had all but vanished.
Over time, spots began to appear on Grandma's Persian rug and cat. Spots could be found in autos. On damask bedspreads. My gawd, spots were everywhere!!!!!
By the time parents realized those innocuous lidded cups had tiny slits, it was too late. While those tiny slits allowed controlled amounts for hydration of parched toddlers, there were no sensors or regulators to distinguish between the soft tissues of the mouth and the soft cushiony surfaces of carpets or fabrics.
Carpets no longer had indefinite lifespans. Manufacturers ramped up the looms. Miles and miles of carpet fibers were needed because of Welch's grape juice and Hi-C fruit punch. Tiny slits in lidded cups single handedly increased carpet profits. Sure-Fit and Oxy Clean CEOs were tra la la-ing all the way to the bank, too.
You can probably find a bargain-priced Spot Bot on eBay. Get to it.
